About

The Nanophotonic Devices Group at the Technical University of Denmark is seeking a highly-motivated individual to join our team as we develop an on-chip ultra-efficient frequency doubler or second harmonic generation (SHG) device. This device will be heterogeneously integrated with an on-chip frequency comb source for use in optical atomic clock applications.

The successful candidate for this position will hold a PhD in physics or a related field, and will be expected to play a key role in the development of our innovative frequency doubler device. This is an exciting opportunity to join a multidisciplinary team of experts as we work to develop a chip-scale optical atomic clock.

Eligibility

Compared with state-of-the-art frequency doublers, you will push the second harmonic generation efficiency by orders of magnitude. You will investigate the nonlinear effect (second-order nonlinearity) in our developed high-confinement AlGaAs waveguide platform and design a frequency doubler at 1550 nm. The fabrication of the frequency doubler will be performed in the DTU Nanolab cleanroom. You will characterize the in-house fabricated nonlinear components. You will also need to collaborate closely with our partners to realize the full integration of the whole optical atomic clock system.

Your main tasks are listed below:

• SHG device modeling considering the anisotropy in electrooptic coefficients, as well as thermal and electro-optic tuning;
• Process development for ultralow loss electrostatic tuned SHG device;
• Design and fabrication of thermo-optic and electro-optic phase shifters;
• Linear and nonlinear characterization of fabricated SHG devices;
• Design and characterization of hybrid integrated AlGaAs/SiN passive circuits;

You must have a two-year master’s degree (120 ECTS points) or a similar degree with an academic level equivalent to a two-year master’s degree. You should have a background in integrated optics, nonlinear optics, and numerical simulation. Experience in nanofabrication and optical characterization is preferred.

Approval and Enrolment

The scholarships for the Ph.D. degree are subject to academic approval, and the candidates will be enrolled in one of the general degree programmes at DTU.

How To Apply

The online application must be submitted no later than 14 October 2022 (Danish time).

To apply, please open the link “Apply online”, fill out the online application form, and attach all your materials in English in one PDF file.

The file must include:

• A letter motivating the application (cover letter)
• Curriculum vitae
• Grade transcripts and BSc/MSc diploma (in English), including an official description of grading scale
• Recommendation letters (preferred)
• Publication list (if applicable)

Applications received after the deadline will not be considered.

All interested candidates, irrespective of age, gender, disability, race, religion, or ethnic background, are encouraged to apply.

Benefits

The appointment will be based on the collective agreement with the Danish Confederation of Professional Associations. The allowance will be agreed upon with the relevant union. The period of employment is 3 years. The PhD project can start as early as 1 November 2022.
